Turner on Challenges of Regulating Urban Heat

Assistant Professor of Urban Planning V. Kelly Turner joined the Talking Headways podcast to discuss different ways to regulate urban heat. The regional urban heat island effect is a climate phenomenon affecting urban areas with buildings and pavement that absorb and radiate heat, making these regions hotter than surrounding areas. However, Turner noted that thermal images that show land surface temperature can be misleading because they don’t illustrate how people are actually exposed to heat. “When I see interventions being proposed like tree-planting programs, I think we need to be careful and say, yeah, we might be providing shade that will be good for pedestrian thermal comfort — shade’s super important — but we’re not addressing the urban heat island,” Turner said. “What we’re doing is just a drop in the bucket, shifting from one climate zone to a fundamentally different arrangement of trees and buildings that would actually be cooler.”
